@param shellCommand - shellCommand
@param options - {onStdout, onStderr}
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.execute(shellCommand, callback);

executeScript

@param localScriptFile - localScriptFile
@param templateVars - variables to the template if uses ejs in the script
@param options - {onStdout, onStderr}
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.executeScript(localScriptFile, templateVars, callback);

copy

@param localFile - localFile
@param remoteFileLocation - remoteFileLocation
@param options - {onStdout, onStderr}
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.copy(localFile, remoteFileLocation, templateVars, callback)
